![]() When it shows us this stuff, it reconstitutes it. So there we go, okay? So let's take a look at what we've got. Three hundred eighteen records, there was 318 lines in there. ![]() So we can say SELECT COUNT star FROM jtrack. It's kind of like if Postgres would just let us say insert this thing as lines, because often that's it. We've done this before in previous things. I wish there was a way to just tell it's like it's lines, insert lines. Don't parse it at all, because we're only inserting one thing anyway. So the dear CSV, treat each line as just a thing. So Ex01 is actually is ASCII number 1 and Ex02 is ASCII number 2 and neither of those characters are in because really the trick is we're only going to pull one column in and we want the whole line, and we want CSV processing, but then we're breaking CSV processing by telling it the quote is a thing that doesn't exist, and the delimiter is a thing that doesn't exist. Now the copy command is only to this pgsql and so we're going to copy into the jtrack table into the body column from the file library.jstxt as a CSV, now it's not CSV, where the quotes are an irrelevant non-printing character and the delimiter is an irrelevant non-printing character. Now what we're going to do is we're going to pull this in with a \copy command. So if I take a look at this library.jstxt file, you see that it's got this JSON in it, one per line. So the next thing we're going to do is we're going to copy down on a terminal in a terminal, this jstxt file and that was not found, but here we go. The old JSON was, but JSONB is not just a text field. There we go, we're just like that body is JSONB and B stands for better but I like to think of it as binary because it's compressed and it's efficient and the indexes are like really intricate, it knows a lot. I'm going to drop the jtrack table then I'm going to create the jtrack table with a id column and a JSONB body. So I'm going to go in and I'm going to drop this table if this is not going to exist, but it's not there. That's the format to do really simple imports for really simple JSON. And I've got one record per line in here. And so we're going to take a look at my original from many years ago export of my library in iTunes and I've converted it into JSON, and so it's got curly braces and double quotes and colons. Everything we've been doing is leading up to this. In this situation, we're going to start talking just about JSONB in Postgres. … The worst depression since the Great Depression is over, and we're ready to party.Hello and welcome to another Postgres walkthrough. We've sold one, and now, like a lot of people, we're thinking about buying again. ![]() Slideshow: More photos from Oyster Jam Music Festival and Boat ShowĪmong boat show visitors who were making detailed inspections of some of the boats was Gainesville real estate salesman Chris Curry, who came with his wife and two daughters. But the savings on fuel would only take a few years to make the solar-powered boat the more economical option, he said. ![]() Then he conceded that the $40,000 price tag for the hard-topped catamaran is probably about $5,000 more than someone would pay for a comparable boat that burned a petroleum-based fuel. When asked how much the Loon costs, he said, "I can tell you what it doesn't cost, which is $5 a gallon for fuel." And he is planning a trip by solar-powered boat from Jacksonville south into Central Florida, he said. Gisborne said he has sailed one of his company's solar-powered boats across the state of New York on a 12-day cruise along the Erie Canal. ![]()
